[jira] [Created] (HIVE-10982) Customizable the value of java.sql.statement.setFetchSize in Hive JDBC Driver

Bing Li created HIVE-10982:
------------------------------

             Summary: Customizable the value of  java.sql.statement.setFetchSize in Hive JDBC Driver
                 Key: HIVE-10982
                 URL: https://issues.apache.org/jira/browse/HIVE-10982
             Project: Hive
          Issue Type: Improvement
          Components: JDBC
    Affects Versions: 1.2.0
            Reporter: Bing Li
            Assignee: Bing Li
            Priority: Critical



The current JDBC driver for Hive hard-code the value of setFetchSize to 50, which will be a bottleneck for performance.

Pentaho filed this issue as  http://jira.pentaho.com/browse/PDI-11511, whose status is open.
Also it has discussion in http://forums.pentaho.com/showthread.php?158381-Hive-JDBC-Query-too-slow-too-many-fetches-after-query-execution-Kettle-Xform
